Abstract: An aluminum alloy clad material can produce a heat exchanger tube that exhibits excellent outer-side corrosion resistance when formed into a tube. The aluminum alloy clad material has a three-layer structure in which one side of a core material is clad with an inner cladding material, and the other side of the core material is clad with a sacrificial anode material, the core material being formed of an Al—Mn—Cu alloy that includes 0.6 to 2.0% of Mn and 0.03 to 1.0% of Cu, with the balance being aluminum and unavoidable impurities, the inner cladding material being formed of an Al—Mn—Cu alloy that includes 0.6 to 2.0% of Mn and 0.2 to 1.5% of Cu, with the balance being aluminum and unavoidable impurities, the sacrificial anode material being formed of an Al—Zn—Cu alloy that includes 0.5 to 6.0% of Zn and 0.03 to 0.3% of Cu, with the balance being aluminum and unavoidable impurities, and the relationship “Cu content (%) in sacrificial anode material≦Cu content (%) in core material≦Cu content (%) in inner cladding material” being satisfied. The aluminum alloy clad material may have a two-layer structure that includes the core material and the sacrificial anode material.
